HELP!! I have a 2018 F150 powestroke diesel. We are travelling with a trailer. We have 4 way, left signal, right signal and brake lights but no running lamps. For some reason, both 4 pin and the 7 pin have no power at the plug in. I haven’t been able to back trace to the main box wire harness. We did find 2 blown fuses...# 43 and 53. Replaced those but still no power. Are there any other fuses to look at? On first glance, the truck wire harness appears to have no damage (trailer harness as well).

We need to drive in the dark. Is there any way to set up temporary running lights on the trailer? All of the running lights on the truck are operational.

Thank you!

 

I would lay under rear of truck and unplug / replug various trailer wiring plugs. Has it been raining?
edit: sorry I had a link, wrong generation

 

Hahahahaha!! We don't have hardly any rain where we live!
